Methods and apparatus for generating arbitrarily addressed, arbitrarily shaped tiles in computer graphics systems.

摘要

Methods and apparatus for rendering graphics primitives (110) to display devices (100) in a computer graphics frame buffer system are disclosed. The methods provide providing an array of addressable video random access memory (VRAM) chips associated to form the graphics frame buffer (80). The VRAMs in the frame buffer (80) are addressed with coordinate pixel locations on the display device (100) corresponding to locations of the graphics primitives (110) on the display device (100). Furthermore, the frame buffer (80) is accessed with a graphics renderer (115) according to arbitrarily shaped tiles (72) containing pixels such that the pixels within the tiles (72) have potentially different VRAM addresses (x, y).
